The folks over at 9to5Mac were sent a screenshot showing the inventory listing of the Radio Shack, and on it is an entry with the description “16GB SPRINT APPLE IPHONE 5″ alongside other entries for the Verizon and AT&T iPhone 5. Assuming the picture wasn’t doctored, this is pretty good confirmation of the iPhone 5 arriving on Sprint.

Fortunately the official iPhone announcement is going to take place tomorrow, and we’ll know for sure by then. Stay tuned to Ubergizmo – we’ll be keeping you updated with the details as they are unveiled. iPhone 5 with unlimited data – I can see some of you already drooling. Who’s excited?
